Description

なお、反射率曲線は、反射率（値）と各波長（値）との関係を示し、色を識別する指標として用いることができる。反射率曲線は、光源からの発光（基準光）に対する反射率を測定することによって求めることができる。具体的に、反射率の測定は、分光測色計を用いて行うことができる。例えばコニカミノルタ株式会社製の分光測色計ＣＭ７００ｄ（商品名）を用いて行うことができる。 The reflectance curve indicates the relationship between the reflectance (value) and each wavelength (value) and can be used as an index for identifying the color. The reflectance curve can be obtained by measuring the reflectance with respect to light emission from the light source (reference light). Specifically, the reflectance measurements may row Ukoto using a spectral colorimeter. For example, it can be performed using a spectrocolorimeter CM700d (trade name) manufactured by Konica Minolta.
